VALVE HECHAIHISK FOB GLASS MAC.

' Application filed February 4, mt Serial nae-12,347.

Toall whom it my camera:

it known that l, AIBERT R. Barman, a citizen of the United States, residing at Minotola, county of Atlantic, State of New Jersey, have invented a new and useful Valve Mechanism for Glass Machines, of wh ch the following is a specification.

My present invention comprehends a novel construction and arrangement of a perfoed.

cam operated valve attachment which although especially designed to be employed in conjunction with glass machines is not ated to such use but may be employed in any case wherein a plurality of valvesare used, the number ofwhich de nds upon the number of operations whic are to be lt further comprehends a novel construc: tion of valve mechanismwherein a driven loosely mounted on said shaft and forming part of a clutch whereby all the cams can be rendered operative upon the proper actuation of a clutch lever to control the admission of motive fluid to operate a number of.

' i ve satisfactory and. reliable results, al-

shown and described.

tough it is'to be understood that the various instrumentalities of which my .inven tion consists can be variously arranged" and organized [and that my invention is nothin ited to the recise arrangement and organization of t ese instrumentalities as herein Figure 1 represents, in nt elevation, a

valve attachment, embodyin my invention.

' Figur e 2 represents a section on line 2-'-2 '1: 3 represents a section on lime-3 1 Similar numerals of preference indicate corresponding parts to the .sitionby means of, a set screw 10.

has adjustably mounted thereon a plu rality of cam supports to which cams are adapted to be adjustably connected, said supports being carried by a sleeve 1 designates standards inwhich is jourhailed a shaft 2 which in a glass machineaft 2 has loosely mounted on it a clutch sleeve 3 havingoa clutch arm a which is adapted to co-operate with the clutch arm 5 carried b a co-operating clutch member 6 which is eyed to the shaft 2, as indicated at 7, in order that it can be longitudinall adjusted thereon. The sleeve 3 is provided wltli' a longitudinally extending groove 8 in order to adapt it to adjustably receive a cam block or support 9 which issecured in its adjusted h e sleeve 3 is of such length that any desired number of such cam blocks or supports can be secured to it in accordance with the number of operations which are to be independently controlled. The cam support 9 is provided with an annular groove 11 formed in a boss or enlargement 112 and secured in the groove 11 by means of fastening devices 13 which pass. through apertures 14 is a cam leaf 15 provided with a curved periphery 16 and with the end faces 17 and 18, respec- Q tively. I provide a series of apertures 14 in order that a cam leaf 15 can be secured at any desired point on the periphery of the cam support. A

The cam face 16 of the cam 15 is adapted to bear against the under face of an arm 19 which is pivotally supported at 20 in a bracket 21 which is secured by meanspf fastening device 22 to a casing 23 which.

forms a manifold and which communicates The chamber 25 of the'casing 23 which is in communication with asource .of fluid supply communicates by means of ports 26 with. the respective valve support 27, it being understood that a separate ort is provided for each valve support; e valve support 27 is provided with a ehamber28 communicating witli'a port 26 and witha rt 29 munication with an annular groove 30 which latter places the chamber 28 in com- I valve casing 33 which latter is provided uwith a valve chamber 34 in which is adapted tov reciprocate a' double headed valve 35 which is moved in one direction by means of a spring 36 in order to maintain the valve stem 37 in contact with the arm 19 which actuates it. The valve casing 33 is provided with ports 39 which communicate with an annular groove 40 which is in commumcation with a pipe 41 leading to the mechanism to be controlled, it being understood that live motive fluid will pass through the pipe 41' when the in Figure 2.

The valve casing 33 is also provided with rts 42 which communicate with an annu-' ar groove 43 with which is in communication the exhaust ports 44 which lead from the mechanism which is being controlled, it being seen that when the parts are in the position seen in Fi re 2, the exhaust from the mechanism belng controlled can take place through the pipe 44, groove 43, port 42 and the open end 31 of the valve casing.

The upper end of the casing 33 is provided with a vent 38. The valve casing is also to a fixed point such as, for example, the

manifold casing 23.-

The operation of my novel mechanism will t now be apparent to those skilled in this art to which my invention appertains and is as I follows I employ as many valves and their controllin means as may be necessary to perform t e difl'erent operations in the cycle of any type of machine such as, for example a glass machine used in the manufacture of glassware. The sleeve 3 which is loosely mounted onthe shaft 2 has fixed thereon in proper position the desired number of cam supports 9 and the sleeve adjusted to its a proper position by means of the hand wheel 52 mounted on the sleeve, the set collars 53 and 54 retaining the parts in their proper around their periphery so that the cam leaf. .15 can be secured to their respective cam sup ports by means of the fastening devices 13 position on the shaft 2 with respect to the clutch collar 6, The cam supports are provided with a row of apertures 14 Q spaced m such a manner that they will operate their independent valve mechanism at the desired time duringtthe rotation of the sleeve 3. The driven sha 2 normally rotates freely within the clutch sleeve 3 but when the lever is parts are in the position seen r actuated to brin the clutch member 5 into the path of the c utch member 4, the sleeve 3 i will rotate in unison with the shaft 2, as

is evident. This causes the valve 35 durin each revolution of the sleeve 3 to be move outwardly byvthe arm 19 and the cam 15 in order to permit live motive fluid to pass from the chamber 25 of the manifold through the port 26, chamber'28, groove 30, ports 32 in the valve. casing into the valve chamber 34 and therefrom to the port 39,

roove 40 and pipe 41 to the mechanism to fie controlled; The exhaust takes 'place as already described through the pipe 44. As

soon as the cam 15 passes out of contact with the arm '19 the spring 36 moves the valve 35 downwardly thereby permitting live motive fluid to pass from the valve chamber 34 through the port 42, groove 43 and pipe 44to the mechanism control to actuate it in a reverse direction from that in which it was formerly actuated. The exhaust from such control mechanism now takes place through the pipe 41, groove 40, ports 39, valve chamber 34 and the vent 38.

It will be apparent that in accordance with my present invention each operation of the machine control can be performed by its own independent valve and the o 1'- ations of all ofthe valvesare controlle by the manually actuated lever 50.

Itwill nowbe apparent that I have devised a novel and useful construction of a valve mechanism 'for glass machines which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a which will give in practice satisfactor and reliable're'sults, it 1s to. be understoo that such embodiment is susceptible of modification in various particulars without departing from the splrit-or scope of the invention or sacrificing an of its advantages.

Having thus descri d my invention, what I claim as new and desire to secure by Letters Patent is: 4

1. A valve attachment comprising a driven shaft, a clutch sleeve loosely. mounted on said shaft, a clutch collar keyed to said shaft and adapted to cooperate with said clutch sleeve, a lurality of cam supports carried by said s eeve each of said cam sup-' ports having'anannular groove therein, a cam member circumferentially adjustable in said groove, means to fix a cam member in its adjusted position, an independent valve mechanism independently controlled h each cam member and a hand wheel carried by said clutch sleeveiwhereby the clutch sleeve preferred embodiment thereof 4 can be partially rotated to determine the proper location of the cams and thereby'the tuning of the operation of said valve mechamsm.
